EDWARD B; HESS, NEW YORK, N. Y., ASSIGNOR TO ROYAL TYPEWRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NIEHV JERSEY.

WRITIN G-MACHINE.

To all whom it may concern:

Be it known that I, EDWARD B. Hess, a citizen of the United States of America, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in \Vriting-Machines, of which the following is a specification.

This invention relates to paper table, and carriage stop devices in a type bar machine. It is indicated as applied to a front strike machine, such, for instance, as those manufactured by the Royal Typewriter Company and well known in the market.

In front strike machines the margin and tabular stops are mounted upon the carriage .in rear of the platen and cooperate with a center stop on the frame. The usual paper table therefor overlies these devices which are rendered more or less inaccessible notwithstanding that usually the upper part of the paper table is so constructed and mounted as to be swung forward to afi'ord some measure of access to the margin and tabular stops.

This invention provides for swinging the paper table rearwardly so as to entirely uncover the carriage stops which are then in plain sight of, and easily accessible to, the operator.

In the accompanying drawing: Figure 1 1s a plan view showing the paper table: Fig.

2. a section on the line 2 2 of Fi 1: Fi 3 a section on the same line showing the parts in different position: Fig. 1, a view between a plan and elevation taken from the point of view of the operator seated in front of the machine: Fig. 5, a detached side elevation: Fig. U, a perspective view showin the rear corner of one of the side plates of the carriage: and Fig. 7, a detail perspective view showing one end of the tabular stop rail and one end of aspring pressed retaining rod that normally bears upon all tabular stops and holds them in position on the tabular. stop bar.

The side plates of thecarria e are indi-' cated bv 1, 1. The platen may e mounted as usual between these plates in front of the parts illustrated in the drawing. At the upper rear corner of each of the side plates is a hollow boss 2 in the bores of which lit the reduced ends of a margin stop bar 3 that asses also through the side plates and are ield by clamp nuts 1. On the margin stop Specification of Letters Batent.

bar are adjustable margin stop frames 5 having spring latches as usual to engage the notches in thebar which latches are provided with enlarged thumb pieces 6. Their stop faces are formed by the heads of adjustable screws 7 fitted in projections S at the rear sides of the margin stop frames. The margin stop devices are in general outline of a construction now well known and heretofore shown in U. S. Letters Patent to me. They are capable of adjustment along the bar and are retained by'the spring latches in any positions to which they may be adjusted. Side bars 9 forming part of a rearwardly projecting frame are mounted to rock upon the bosses 2 and are held in a normal horizontal position by forwardly projecting stop pieces 10 on their front ends that engage the underside of the transverse rod 11 extending between the side plates. For the moment, it may be considered that there is a rearwardly projecting frame of which 9, 9, are the side bars irrespective of the fact of its being capable of being rocked upwardly and forwardly.

. At a'suitable distance in rear of the margin stop bar there extends between the side bars 9, 9, a notched tabular bar 12 to the ends of which are applied retaining nuts 13.

The tabular stop bar may receive a series of individually adjustable tabular stops or plates of any appropriate construction. Those illustrated and. indicated by 14 in the drawing are bifurcated at the bottom to straddle the tabular bar and their front lugs engage the notches in the .front face of the tabular bar. These tabular stops are of appropriate dimensions and at their rear edges each is formed with a corresponding circular recess 15 in which normally lies a spring This bar 16 is provided with knurled heads and is carried in two rockers 17 one at each side of the carriage respectively mounted to turn about stud bearings 18 around which are disposed coiled springs 19 the reaction of which tends to-urge the rockers forward and maintain the bar16 in position, as shown in Fig. 2 for instance, to prevent disengagement of the tabular stops from their bar. The rocking plates 17 are formed with stop faces 17 that contact with the top face of the tabular bar 12. To release any or all of the tabular stops for removal or adjustment, it is only necessary to press back the bar 16 when any one or all of the tabular stops may be removed or re-set,

Interposed between the margin stop bar and the tabular sto bar is a center stop rocking fore and aft of the machine and which may be constructed and have the mode of operation set forth in my Letters 'Patent No. 874,892 granted December 24, 1907;that is to say, the part 20 of such center stop indicated in Fig. 4 is the upper end of a lever capable of being rocked fore and aft of the machine and is that part of the center stop that enga es the margin stop 7. The other part 21 of the center stop is a yielding plate rocking about an axis at right angles to that on which rocks the part 20 of the center stop. ,The plate 2l'engages the= tabular stop and when a tabular stop is engaged it part 20 of the center stop. As described in the patent referred to, this t-ransverse'movement of the plate 21 is made effective to throw into operation line lock devices. The paper table 22 is carried by plates 23 arranged transversely of the machine and forming the bent ends of side plates 24 that rock about ivot bolts 25 mounted in the side bars 9, 9, of lzhe rearwardly projecting frame. The normal position of the paper table in which it acts to guide inserted sheets to the platen is that shown in Fig. 2, the side plates 24, 24, then resting upon the top face of the margin stop bar 3. In this osi'tion as usual it covers more or less the ta ular or margin sto devices and renders them more or less diflihult of access.

As shown in 3, however, the swing-J ing plates 24 carryin the a er table may be swun backwardly until tl iey rest upon the tabu ar stop retaining bar 16. In this position, the. mar in and tabular stop devices are complete y exposed to view and are entirely accessible to the operator. If it is then desired to adjust any of the tabular stops the retaining bar 16 may be pressed rearwardly ,by direct manipulation of it or by exerting" downward pressure on the paper table, the side plates 24-thereof forcin the bar out of engagement with the ta ular stops. The rearwardly projecting frame, of which 9 are the side bars, may be swung upwardly and forwardly as shown in Fig. 5 so as to remove the tabular devices and paper table from their normal position thereby aifording ready access to the center stop, escapement devices, rear of the machine.

I claim:

= 1. A writing machine having a transversely movable carriage, a revoluble platen thereb an ad ustable carriage stop stop and means whereby the tab yields until it comes against thesaid stop to the view upwardly and rearwardly and other parts at the state? located in rear of the platen, a paper table normally interposed between the laten and e may be moved upwardly and rearwardly away from the platen to uncover the stop to the view and convenient access of the operator.

2. A' writing machine having a transversely movable carriage, a revoluble platen carried thereby, a series of adjustable tabulator stops located in rear of the platen, a paper table normally interposed between the platen and the tabular 'stops and means whereby the table may be moved upwardly and rearwardly away from the platen to uncover said stops to the view and convenient access of the operator.

3. A writing machine having a transversely movable carriage, a revoluble platen carried thereby, an adjustable margin stop located at the right hand side of the carriage and in' rear of the platen, a paper table normally interposed between the platen and said margin stop and means whereby the table may be moved upwardly and rearwardly away from the platen to uncover Y and convenient access of the operator.

4. A writing machine having a transversely movable carriage, revoluble platen carried thereby, an adjustable carriage stop located at the right hand side of the carriage frame pivoted in rear of the transverse line in which the stop is located and adapted to be'swung upwardly and rearwardly and a paper. table carried by said frame and normally located between the platen and stop but moving with the frame upwardly and rearwardly to uncover the stop to the view and convenient access of the operator.

5. A writing machine having a transversely movable'carriage, a revoluble platen carried thereby, a support pivoted at its rear end in the carriage and'extending forward toward the platen and a aper table carried in the front end of said support, whereby the support may be swung upwardly and rearwardly to carry the table rearwardly bodily away from the platen.

6. A writing'machine comprising a rearwardly projecting frame mounted to rock upwardly about an axis at its front end, a swinging frame carried by said rearwardly projecting frame and adapted to be swung and a paper table carried by the latter frame.

In testimony whereof, I have hereunto subscribed my name. I
